CARPET-SWEEPER.

SPECIFICATION forming part of Letters Patent No; 329,374, dated October 27,1885.

Serial No. 155,712. (ModeL) To all whom it may concern.-

Be it known that I, WALTER J. DREW, a citizen of the United States, residing at Grand Rapids,Kent county, Michigan, have invented new and useful Improvements in Carpet- Sweepers, of which the following is a specification.

My invention relates to carpet-sweepers; and the purpose thereof is to provide a case having such construction that it can easily be swung open and the dust and sweepings discharged therefrom, the construction being such that by the opening of the case the brush is drawn away from its top and an unobstructed passage provided for the discharge of the sweepings from both pans.

The invention consists in the several novel features of construction and combinations of parts hereinafter fully described, and definitely pointed out in the claims.

Referring to the drawings forming part of this application, Figure 1 is an end elevation of the sweeper constructed in accordance with my invention. Fig. 2 is a central transverse section of Fig. 1, showing the case opened. Fig. 3 is an end elevation of a sweeper-case having a slightly different construction in which my invention is embodied. Fig. 41. is a crosssection of Fig. 3, showing the case opened. Figs. 5. 6, and 7 are end elevations of sweepers of different construction in which the invention is embodied, the full lines showing the case closed, while the dotted lines show the same opened.

In the said drawings, the reference-numeral 1 denotes the sweeper-case, which is constructed in two parts or sections, 1 and 1". These parts are united by straps 2, fastened upon the ends of the section 1 and projecting beyond the same, their ends receiving pivots 3,which enter the ends of the sections 1". The edges of the metal straps 2 project slightly above the margin of the section 1 and serve to conceal in part the out which divides the easing.

Referring to Figs. 1 and 2, the brush-shaft 4hasjournais 5, which are mounted in bearings 6, the latter forming part of or rigidly mounted upon plates 1), which are pivoted at the point 2) upon the inner faces of the sections 1. (gee Fig. 1.) Upon the ends of shaft 4 are mounted friction-pulleys 7, which are pressed against driving-wheels 8 by the action of spring 7, connected to the ends of thepivoted platesb, the driving-wheels being mounted upon bearings 3 in 'the section 1, said bearings forming also pivots upon which the straps or bars 2 swing when the casing is being opened and closed. By pivoting these bars upon the axis of the drive-wheels the friction-pulleys 7 will at all times be held in engagement with the driving-wheels, and the journals of the brushshaft be retained in their bearings as the casing is opened and closed. The pans 9 and 10, which are essentially of the usual form, are mounted upon each section of the divided case. I prefer dividing the case by means of a vertical cut,which extends from the lower edge of each end of the case to a point somewhat above the axis of the brush- 7o shaft, and thence toward the front of the case. By this construction the casing is divided into two unequal parts, as shown in the drawings, the brushshaft 4 being in all cases carried by the section 1. The other section,1", comprises the entire top and upperportion of the casing, together with the rear part thereof, which carries the drive-wheels. This enables me to mount the handle upon any portion of the casing. WVhat is of more importance, however, is the fact that by the construction described the case is opened by simply dropping the section 1 by gravity, the sweeper being meantime supported by the handle. WVhen opened in this manner, the section 1 is emptied by merely swinging it toward the rear from the position shown in Fig. 2, the sweepings passing out over the inclined front wall. The other section,l",is then emptied by reversing the position of the parts, turning the open 0 casing upon the handle as a pivot, whereupon the sweepings contained in the pan 10 pass out over the roof the box. In this manner danger of discharging a portion of one section into the other or upon the brush is effectually avoided. 9 5 NVhen the casing is opened,-the brush and the top of the casing will be separated, the former dropping downward and away from the top of the sweeper-case. As a result of the construction described, also, the brush is drawn away from the front of the pan 10, which is carried by the section 1", and an unobstructed passage is provided for the sweepings, which pass out over the inner surface of the top of the casing.

This invention may be applied to various patterns of sweepers without essential alteration.

In Figs. 3 and 4 I have shown a sweeper having the operative parts arranged and operated differently, but in all substantial particulars the invention is the same as that already described. In said figures, also, a spring, 11, is shown having its ends attached to the sections 1 and 1", above the pivot upon which the parts turn. This spring draws the pulley of the brushshaft against the drivingwheel, and also throws the section 1 toward the part 1 and keeps the casing closed. It

I is evident, however, that this spring is not an essential element, as the casing may be provided with a suitable fastening, such as the spring-catch l2. (Shown in Figs. 1 and 2.)

In theremaining figures of the drawings still other patterns are shown, in each of which my invention is embodied. In all cases the pivotal axis upon which the sections of the divided case turn is either coincident with or below the axis of the driving-wheels 8,whereby the entire top of the case is preserved integral, and the section carrying the brush swings downward, drawing the brush away from the top and the front of the pan, and leaving an unobstructed passage for the sweepings, as already described.

This invention permits the use of two dustpans and provides simple and efficient means for discharging the sweepings from both. It may be applied to any class of sweepers in which the brush is driven by any of the wellknown forms of gearing.

Having thus described my invention, what I I claim is- 1. A carpet-sweeper having its casing divided into two unequal parts or sections, one comprising the entire top and rear portion and carrying the driving wheels,and the other carrying the brush, the latter section being pivotcarrying the brush-shaft, the latter section being pivotally connected to the former at a point coincident with or below the axis of the drive-rolls, substantially as described.

3. In a carpet-sweeper, the combination, with a casing divided into the sections 1 and l",

. of a brush carried by the former section, drivewheels carried by the latter section, straps or bars pivotally connecting the section 1 to the section 1 at a point coincident'with or below the axis of said driving-wheels, and pans carried by both sections, substantially as described.

' 4. In a carpet-sweeper, the combination, with a casing divided into two unequal secsions, l and 1", the former carrying the brush and the latter comprising the entire top of the casing and carrying the driving-wheels, of straps or bars pivotally connecting the section 1? to the section 1 at a point coincident with or below the axis of the drive'wheels and WALTER J. DREW.
